PROBLEM TO BE SOLVED: To reduce erroneous recognition when recognizing a plurality of types of touch operations on the basis of a proximity state between a recognition object and a touch object surface, even in the case that the touch object surface is not a plane uniform in height.SOLUTION: An information processor for recognizing a touch operation with a recognition object detects an indicated position indicated by the recognition object, acquires information indicative of a surface shape of a touch object surface, and determines whether the touch object surface is touched with the recognition object or not on the basis of the detected indicated position and the acquired information indicative of the surface shape of the touch object surface. When the recognition object is moved in touch with the touch object surface, it is determined whether the touch object surface is touched with the recognition object or not on the basis of information indicative of a surface shape on a path along which the recognition object has been moved, out of the acquired information indicative of the surface shape of the touch object surface. |
